あり、それらの作用効果は以下の通りである。To achieve this object, a characteristic feature of the water treatment apparatus of the present invention is that a water treatment tank in which a solid-liquid separation membrane is immersed is provided, and an opening is formed in a wall of the water treatment tank. And a cylindrical body projecting outward from the water treatment tank over the entire circumference is continuously formed on the peripheral edge of the opening, and a flange is integrally formed with a distal end edge of the cylindrical body. In the flange portion, a door capable of closing the opening portion is provided detachably, and at least the lower inner surface of the cylindrical body is formed on an inclined surface that becomes lower as it goes inside the water treatment tank. The characteristic configuration of the water treatment apparatus of the second invention is as follows.
A water treatment tank in which the solid-liquid separation membrane is immersed is provided, an opening is formed in the wall of the water treatment tank, and a cylinder projecting outward from the water treatment tank over the entire periphery of the opening. A body is continuously provided, and a flange portion is integrally formed at a distal end portion of the cylindrical body, and a door capable of closing the opening is detachably provided on the flange portion, and an inner surface of the cylindrical body is provided. Is provided at least at the lower portion with an inclined surface forming member having an inclined surface whose upper surface becomes lower as it goes inside the water treatment tank, and their operation and effect are as follows.

Since the lower surface of the cylindrical body is an inclined surface by attaching the inclined surface forming member having an inclined surface that becomes a low position, solid matter such as sludge in the water treatment tank is placed inside the cylindrical body. Even if precipitated, it is difficult to deposit. Also, even if it is deposited,
Since the inclined surface is lower in the water treatment tank, sediment deposited on the inclined surface is easy to fall into the water treatment tank,
Even if the door is opened with solids accumulated inside the cylindrical body, it is difficult for the sediment to be dragged out of the water treatment tank, and even if the sediment is out of shape, the outside of the water treatment tank The sediment hardly spilled out of the water treatment tank because it fell more easily inside.

ようになった。As a result, the sediment such as sludge hardly spills out of the water treatment tank, so that the surrounding environment of the water treatment device is hardly contaminated, and the working environment for maintenance of the water treatment device is good. It has become useful for environmental protection around processing equipment.
